HAROLD B. DONLEY, OF COLUMBUS, OHIO, ASSIGNOR TO THE JOHN W. BROWN MANU- FACT'URING COMPANY, 015 COLUMBUS, OHIO, A CORPORATION OF OHIO.

HEADLIGHT FOB, AUTOIVIOBILES.

Application filed October a? To all whom it may concern;

Be it known that I, HAROLD B. DoNLnr, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Headlights for Automobiles, of which the following is a specification.

The present invention relates to improvements in head lights for automobiles.

The primary object of the invention is to provide novel means for tilting the reflector of the headlight so that the light rays thereof can be deflected in such directions as to prevent glaring.

A further object of the invention is to provide a headlight so constructed that the reflector can be easily and quickly tilted and held positively in its tilted position in a convenient manner.

With these and other objects in view, as will appear as the description proceeds, the invention consists in the novel features of construction, combinations of elements, and arrangements of parts, and hereinafter to be fully described and pointed out in the appended claim.

In the accompanying drawing:

Figure 1 is a vertical central sectional view through a headlight equipped with the device,

Figure 2 is a fragmentary'horizontal view taken through the headlight and showing the tilting mechanism in to elevation, and

Figure 3 is a sectional view on the line 3-3 of Figure 1.

Referring to the drawing 1 designates the casing which is of any well known form and is provided with the usual lens 2, said casing being mounted upon the automobile in any suitable manner.

The reflector 3 is of the parabolic type and is pivotally supported within the casing 1 by brackets 1 which may be of any suitable construction. The reflector has associated therewith the incandescent bulb 5 which is mounted in a socket 6 carried by the reflector, said socket having a plate 7 connected therewith and to which is connected the lower end of the coil spring 8, the upper end of said spring being connected with the top of the casing 1, said spring serving to yieldably hold the reflector 3 in its tilted or normal position.

Mounted upon the bottom of the casing 1 1922. iierial No. 597,3Q6.

is a housing 9, said housing having an annular groove 10' formed therein and in which is located a coil spring 11, the purpose of which will appear later. This housing has formed integral therewith a block 12.

To the lower end of the reflector 3 is riveted a bracket13 which is provided with spaced ears 1 1, and between which is pivotally connected the forward end of the rod 15, said rod being slidable in bearings 16 formed in the ends of thehousing 9. This rod isprovided centrally with a head 17, said head being longitudinally curved so that it will be held in adjusted positions within the housing 9 when the rod is shifted. As shown in Figure 1 of the drawing the head is in its rearmost position and at which time the coil spring 11 is engaged with the forward end of said head thus holding the shaft 15 in the position as shown, in

an obvious manner. When it is desired to move the reflector 8 to its normal position it is only necessary to shift the rod 15 forwardly whereupon the spring 11 will engage the rear end of the head 17, thereby holding the rod 15 in its forward position. As shown in Figure 1 the reflector is in its tilted position, and as before stated the head 17 is in its rearmost position.

The block 12 is provided with a bearing 18 which has its lower end opening into an annular recess 19 also formed in the block and in which is rotatably mounted the collar 20 of the shaft 21, the upper end of the shaft 21 being rotatable in the bearing 18. Since the collar 20 is located in the recess 19 upward movement of the shaft 21 is pre vented, and since the collar rests upon the bottom of the casing 1 downward movement of said shaft is prevented, but the shaft is permitted to turn freely within its bearing when described. The upper end of the shaft 21 has fixed thereto in any suitable manner the arm 22, said arm being provided with furcations 23 between which is pivotally connected the rear end of the rod 15. The lower end of the shaft 21v terminates in an angular-1y disposed arm 24. which has pivotally connected thereto the forward end of the link 25, said link being extended rearwardly so that it can be conveniently manipulated by the driver of the car to operate the reflector when desired.

It will be obvious that when the rod 15 is in the position as shown in Figure 1 that turn the refiector3 to its normal position it is only necessary to inove the link 25 foiardly whereu on; the shift 21 Will be rocked and consequently the arIn ZQ WiH be swung forwardly thus compelling the fund v15 to move forwardly until the head 17 c trried thereby is in the'foi'yya'i 'd end'of the Mu n Wi which time g c nlr i Wi11 ,se'rve tojhol d the ham a'giti'r'it a ci n-e r a wa d m mfifif e i I From the foregoi g d'c'npt onit W111 fgositionnfter tlielightmy been deflected downwardly. lFurther Will be Observed theft by inountinfg thc haft 21 the manner shown tht entrance of'inoiture and duet to the intei ibr hf the' czts iiig is pie'x cfitd.
